To all whom it may concern;

Be it known that I, FREDERICK W. HALL, a citizen of the United States, residing at Camden, in the State of New Jersey, have Invented certain new and useful Improve ments in Bottle-Sealing Devices, of which the ollowing is a full, clear, and exact dehad to the accompanying drawings, forming a part of this specification.

My invention relates to that class of boting devices comprising a hard metal 0 In suc sure is effected by external y a suitable toolon the crown of the cap,

I the cap with the bottle head without requiring any bending of the metal of the flange afiundthe' pro-.

ecting annular shoulder of the bottle. This is effected by my novel. construction of the vcap flange hereinafter described, providing groove; of a compressible sealing medlum,

within the cap and bottle, and a bottle having an annular shoulder below the lip thereof; said elements being so proportioned and arranged that when initially assembled Fig. 3 is a modification thereof showing cap lined With paper. Fig. 4 is a vertical section of the cap, disk and bottle elements in initial position.

cap, compressing t e erspeclocked relation therewith.

e cap element of my hard metal, such as roofers tin, of which such caps are commonly made, and it may be" most cheaply and satisfactorily produced by suitable dies in a stamping-up press. cap consists of'a. crown portion a with integral depending annular flan e b, which is to be continuous and without s its.

is preferablyresilient under compression, below a medial line in the length of the the shoulder of the device is made of Fig. 5 is the same when pressure has been applied to the crown of the ements,

is therefore better adapted to enter the disk, as seen in Fig. 5, and wherein the annular edge h of the bottle shoulder h is shown as rather sharply defined by sloping the portion m of the bottle head, which is between the 70 .extreme upper edge of the li e and the circumferentially largest part of the shoulder 71.

The disk element n is preferably of cork, or some other sealing medium which. is distinctly and appreciably compressible, and I 75 prefera cork disk of about an eighth of an inch in thickness, because under vertical compression it will be resilient, which not only helps sealing contact but tends to exert a continuing upward pull to maintain the 80 parts in said combined and locked relation. As cork however is not always of good qual- -ity and is apt to dry, causing leakage, the cap may be lined with paper as shown at s, Fig. 3, and thus used either with or without 85 the cork disk, but preferably with it. With such paper lining a hermetic seal may be made, as the contact of the lined groove of the flange against the smooth underface of the shoulder of the bottle will at all times 90 revent the access of air to the bottle or to the interior of the cap below the lip of the bottle.

In sealing the device upon the bottle,-the elements are assembled as shown in Fig. 4; pressure upon the crown of the cap will compress the disk and effect a sealed relation between it and the bottle'mouth, such vertical pressure also lowering the flange into a horizontal plane lower by the depth to which the too lip of the bottle has entered the cork disk, as shown in Fig. 5. If the parts are properly made and properly porportioned, the central lane of the groove will coincide with the central plane of the annular projecting shoulder 105 of the bottle, as shown in Fig. 4; but after compression of the disk the plane of the groove will be slightly below the largst circumference of the bottle shoulder, as' shown in Fig. 5, and ready to be sprung into locked no relation thereto, which is as shown in Fig. 6.

An additional and distinct advantage of forming the open inwardly-facing groove with an outwardly-inclined narrow rim beneat-h it is, that when such locking contact is r effected, this rim edge will stand off some- The bottle element of my device is prowhat from the surface of the bottle, due envided with an annular shoulder h below the tirely to the inwardly-inclined under surface mouth of the bottle, and a lip e at some slight of the bottle shoulder, as seen in Fig. 6, af-

flange (depending upon the distance between the hp e of the bottle and its shoulder h at its greatest circumference) the flange is formed with an annular narrow groove 0, which is to 5 be constructed as an open groove, and with its wall facing inwardly, leaving a narrow portion d of the flange below and extending from the lower wall of this groove or head 0, which is to be slightly expanded outwardly so as to 10 form a narrow edge rim slightly inclined outwardly from the vertical.

lhe action of the forming-dies in compressing the metal to form the inwardly-facing open groove 0, in conjunction with the 1 5 co-acting dies which slightly expand the edge rim (Z below the lower wall of the groove, in giving suchrim an outward'incline,results in a construction in which the said expanded rim may be afterward readily compressed, by very slight radial pressure on its extreme annular edge, while it is obvious that under such compression, the force applied to the edge of the rim (1 will extend to the lower wall of the open and inwardly-facing groove 2 5 and, without bending the metal at all, at any oint where it touches or may touch the glass, will operate to spring the annular edge of the groove under the shoulder of the bottle, because the consequent effect ofradially com- 0 pressing the said narrow flange rim cl into the same vertical plane with the up er cylindrical portion of the flange above the groove, is to slightly contract the circumference of the annular edge of the inturned open 3 5 groove, and this without in any sense binding the metal of any part of the flange which can or may contact with the glass in effecting such locking relation. It is quite true that such reduction of circumference of the inner o edge of the groove is very small, in fact is merely line-like in extent, but it is quite sufiicient to lock the cap securely on the bottle head, for if said inner wall of the groove is reduced in circumference, even to the slightest appreciable extent, below the greatest circumference of the bottle shoulder, it will be impossible to remove it from the bottle w ithout again expanding the mm (1 into the initial form and circumference, which it had when applied to the bottle (as shown in Figs. 4

and 5.)

In forming the lip e and shoulpensive cap-setting machines being used for der h, I prefer the form shown in the drawthe purpose. With my device the simplest ings, wherein the lip e is somewhat thin and kind of setting machine, requiring very little I 3 the inner diameter of which is slightly larger than the outer diameter of the crown cap,

1 said metal sealing cap havin hence striking in its descent, the extreme edge of the inclined rim of the flange below the groove, and bringing both into the position shown in Fig. 6 wherein the inner annular edge of the groove has been slightly contracted in circumference and thereby sprung beneath the bottle shoulder, and sald rim of the flange though vertical, stands ofl from the under inclined surface of the bottle shoulder.

Having thus described my' invention, I claim. as new and desire to secure by Letters Patent l. A hard-metal sealing cap having a diskshaped crown with an integral and continuous annular flange which is provided intermediate its length with an inturned open roove and an outwardly inclined rim edge elow and proceeding from the lower wall of roove.

below it a rim edge initially inclined outwardly, whereby when radial pressure is applied to said inclined rim edge to bring it into I substantially the same vertical'plane with the portion of the flange above the groove, the inner annular edge of the groove will be slightly contracted circumferentially and sprung into locked contact with the underface of the bottle shoulder.

3. A sealing device comprising a bottle having a head provided with a pro] ecting annular shoulder between its lip and neck, a compressible sealing medium, and a hard metal sealing cap having a continuous flange provided intermediate its length with an open and inturned annular groove and a depending rim roceeding from the lower wall thereof, sai groove being brought into locked relation to the annular shoulder of the bottle. v

4. A sealing device consisting of the combination with a bottle having a projecting annular locking shoulder between its lip and neck, a compressible sealing disk under sealing pressure on the lip of the bottle, and a paper-lined hard metal sealing cap having a continuous annular flange provided intermediate its length with an open inturned annular groove and an annular rim edge proceeding from the lower wall thereof, and which is brought into a substantially vertical plane whenthe groove of the cap is in locked relation to the bottle shoulder.

In testimony whereof, I have hereunto affixed my signature this twenty sixth day of April A, D. 1906.
